# DF Market Intelligence – x402 Service Rankings

> DF Market Intelligence – x402 Service Rankings is a paid API for AI agents from df-data-agent.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Returns ranked x402 paid-API services by 30-day call volume, unique payers, or estimated revenue, with endpoint counts, median prices, supported networks, and a concentration filter to exclude thinly-traded services.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability df-market-intelligence-x402-service-rankings-c8988f15
```

Example prompt: Show me the top 25 x402 services ranked by unique payers in the onchain_data category, filtering out any services whose volume comes from fewer than 5 wallets.

## When to prefer this

Choose this endpoint when you need a ranked, filtered leaderboard of x402 paid services with volume, payer, and revenue signals — especially when you want to exclude low-liquidity services dominated by a handful of wallets. Prefer it over the general x402 economy summary endpoint when you need per-service granularity and sorting control, or when researching a specific category like ai_inference or trading_defi.

## Known failure modes

- Invalid sort value (not calls/payers/revenue) returns a validation error
- Limit out of range (outside 1-200) returns a bad request error
- Invalid category string returns empty results or validation error
- Endpoint may return stale data if underlying Bazaar catalogue has not refreshed recently
- Network errors or provider downtime return 5xx responses

## How this service works

Ranked x402 services (by 30-day calls, unique payers or estimated revenue) with endpoint count, median price, networks and a concentration flag that filters out services whose volume comes from fewer than 5 wallets. Filter by category.

## Output

A ranked list of x402 services, each including service name, 30-day call volume, unique payer count, estimated revenue, endpoint count, median price, supported networks, and a concentration flag indicating whether volume is spread across at least 5 distinct wallets. Results are ordered by the chosen sort field and capped at the requested limit.
